STM32 MCUs Products

Issue starting my microcontroller in my own design.

Dear all, I´m using the BlueNRG-LP microcontroller and STLink-SETV3. My firmware works perfectly in the Steval-IDB011V1 DK. I´m using BlueNRG-LP-X-Flasher Utility v4.1.0 to program the microcontroller through the STLink-SETV3 programmer and I can pro...

Safe multitasking

What is the best way and safer way to make one led blinked and, at the same time, control one motor?

stm32g4 adc & dma &timer

I have stm32g441 Chip. ADC1 used in external trigger  mode and triggered by Time1Channel4 (OC4REF),But when T1Ch1- T1Ch3 worked in Center-aligned mode,T1CH4 has not Worked,ADC1 DMA interrupt occured,and occured in cycle.

STM32H7~How to allocate arrays to a certain location

I tried adding this to the linker file/* used by the startup to initialize data */ _sidata_RAM_D3 = LOADADDR(.data_RAM_D3); /* Initialized data sections goes into RAM_D3, load LMA copy after code */ .data_RAM_D3 :  {  . = ALIGN(4);  _sdata_RAM_D3 = ....

Can STM32G030Kx (LQFP32 package) high speed external clock signal (HSE) be generated from external crystal resonator, or it can be generated from external clock generator ONLY?

In STM32G030x6/x8 datasheet (DS12991 Rev 3, Table 12 on page 31) I see only input pin for external HSE clock source (LQFP32, pin 2 - PC14 - OSC_IN), but don't see OSC_OUT pin of HSE OSC.

STM32L4R5 PWM : Bare metal code| I am writing some basic PWM drivers using the TIM16 and TIM17. While initializing the TIMer register I came to a register TIMx_CCER. Can someone help me withOutput control bits for complementary OCx and OCxN channels.

Using HSEM of STM32H7 ( sharing data )

Hi, I am working in project in which I use an STM32H745, So am trying to share data between the two CPUs.first I create structure in the two CPU like this :I used the same memory addressstruct shared_data { uint8_t drdyM4; float32_t data_to_M7[6][1...
